This forum is all about ebook readers, mobile ones like Blackberries and Kindles and such. VERY geek-intensive, more than most of us need to know. Of course that means a really good chance of finding what we DO need to know.
Reminds me of the "phone phreaks" back in the seventies, these guy cover every reader format and software, converters from mobipocket to pdf to html to epub or whatever. Exhaustive resource for ebook creation and reading, is my impression.MobileRead.com
